No, only specific species within the Merginae subfamily are classified as sea ducks, based on biological adaptations to saltwater.
Sea ducks are diving ducks that feed underwater, while seagulls are seabirds that typically scavenge or feed on the surface.
Threats include habitat degradation, oil spills, overfishing of prey, and climate change affecting their marine ecosystems.
